But, do you have plastic milk jugs and glass baby food jars full of used, rusty, bent nails with no heads on them, you kept for decades??.....My dad did. Every damn time I wanted to nail something together as a kid, I had to search and search for the least bent nail, that had something that resembled a nail head on one end, try to straighten it out by pounding on it on the concrete floor with a wore out claw hammer that more resembled the rounded part of a ball peen hammer and had one of the two claws busted off, along with tons of used electrical tape wrapped around the head to hold it on....Then I had to take a wore out bastard file and try to sharpen the tip of the nail. One good smack with that hammer ensured the nail bent right back over, never penetrating the board by more than 1/8" along with me getting my fingers smashed....good times....good times......
